Original appilication filed August 30, 1920, Serial No. 407,024. Dividedand this Hovember 3, 1922.

To all whom it may concern:

' Beit known that I, PHILIP A. MYERS, a

citizenof the United States, residing Ashland, in the county of Ashlandand State of Ohio, have invented certain new and useful Improvements inBearings, of

{which the following is a specification, refer ence being had therein tothe accompanying drawing. v v 1 This invention relates to improvedbearings for the shafts employed in a power. head for use in operatingpumps, usually 1 domestic pumps which stand in a vertical position.

In my application, Ser. No. 407,024, filed Aug. 30th, 1920, Patented No.1,437,988, Dec. 5-, 1922, for improvements in this class of power headsI set forth and show a power head with which the present improvementsare used pr of which-they form a part.

These improvements relate to removable bearings for the driving shaftand removable bearings and stud shafts for the driven,

gears which constitute a part of said power head. The peculiarities andadvantages of these bearings will be set forth hereinafter; In theaccompanying drawings;

i Fig. 1 is a transverse vertical sectional view of such a power headwith these improved bearings applied thereto, the view being taken onthe line 1-1 of Fig. 2;

Fig.2 is a vertical sectional view taken onthe line '22 of Fig. 1.

I will not describe'in detail any of the mechanism shown herein, exceptthat which forms the subject matter of this present invention, as suchmechanism set forth in my said application 407,024 referred to above.Generally speaking the numeral 1 designates .a casing, usually of castiron, for containing the pump rod operating-mechanism and a quantity oflubricant. A cover 2 is usually applied to the casing to exclude dustand dirt.

I will first'describe the bearings which are usedto support the drivingshaft 3 which is driven by a tight pulley 4 which carries a loose pulley5, on which the belt may be shifted when the mechanism is not to beoperated. These bearings consist of the cu like portion 6 and a sleeve 7cast integra y and provided witha flange 8 ,h'aving holes for theinsertion of screws 9 which are used to secure the bearings tothe wallof the application filed casing, the latter having screw-threadedapertures 10 to receive these screws. The

up by the gears which dip into the oil with in the casing. The sleeves 7extend into openings 11 in the casing and are provided with an opening12 for the more ready adopening 13 to permit anylubricant enteringthe,opening11 to more readily reach the end of the shaft 3. v

Mounted on" the shaft 3 are pinions 14 which mesh with driven gears 15.It will be noted that the diameter of the openings 11 in the casing wallis greater than that of the pinions. The purpose is to admit of theremoval of the shaft 3, together with the pinions 14 by detaching thebearings 6 next to the pulleys. This alsotfaci-litates in assembling theparts in the course of manufacture. f

A gasket or washer 16 is used to prevent leakage of the lubricant.

Thus it will be seen that I provide simple, strong and readily appliedbearings for the driving shaft 3 and which may be readily assembled withthe other parts and yet which by the attachment of one of them willpermit of the removal "of the shaft and its two pinions. I I

Referring now to the bearings for the driven gears 15 they each consistof a plate 17 having a flange 18 and a sleeve 19 with a shoulder 20. Thesleeve extends through i an opening21'inthe casing, a gasket or washer22 makes an oil,tight joint andv screws 23 secure the plate 17 to thecasing. The sleeve 19 constitutes on its exterior a stud bearing, thatis, a bearing, which pro jects inward from the casing wall and on whichis mounted the driving gear 15. Lu-

bricant will work into this hearing as. it fldrops down "from the ugearing and pinions.

I It will now be seen that these stud bearingsare readily applicable tothe casing and readily removable and that they afford a strong andeflicient support for the driven gears 15 which perform the labor ofoperating through the interconnecting wrist pin 24 the pitman 25 andthence the other deouter-end of the cap portion forms a closure,

mission of the lubricant and also with an pper part of the p 7 TO THE F.E. MYERS AND BROTHER COMPANY, OF ASHLAND, OHIO, A CORPORATION OF OHIO.

entire I k vices which transmit the power and motion to the pump pistonrod.

' These stud bearings also aid in the ready and quick assembling of theparts when the gears are to-be mounted.

Having thus fully described my invention, what I claim as new and desireto secure by Letters Patent, is

"1. In a power head, the combination with a casing adapted to contain aquantity of lubricant and operating mechanism, and provided withopenings in its opposite walls, of a set of bearings consisting of cupsand projecting sleeves each of which extends through one of saidopenings and is of less diameter than such opening to form a lubricantpassage, and fastening devices to removably attach such bearings to thecasing.

2. In a powerhead, the combination with a casing having an opening in awall thereof, of a removable bearing consisting of a cup provided with asleeve which extends through said opening and is'of less diameter toprovide a lubricant passage, means .to detachably secure the cup to thecasing, and

avdriving shaft mounted within the sleeve and provided with a pinion ofless diameter than saidopening in the casing,'wherefurther provided withopenings which lead from the shaft within this bearing to the spacebetween the sleeve and said opening to admit lubricant through saidspace and openings to the shaft, and means to detachably secure saidbearing to they casing.

In testimony whereof, I affix mv si nature.

PHILIP A. MY RS.
